I have ridden my 1325 with winds in the 10 to 13 mph range on my 65L board with my 8m CWC and had fun cruising.
I have only had one chance to try my MA 1750. I took it out in light winds. 7.5 to 9.5 mph per my wind meter. I had it on 935/60/205 on my 7'7 DW board. I only took my 5m V1 mantis wing. I got it to lift but could not fly. I am pretty sure I had the foil too far forward the way I kept stalling. But it was only the first time and still trying to work out the placement. There is definitely potential though. Could have easily flown with a bigger handwing. me 193lb/87kg.
